Analyst: Battery Life Still a Concern for RIM's Playbook, Flash at Fault
Sounds plausible, but according to Kaufman Bros. analyst Shaw Wu, it's still unlikely the PlayBook will offer "anywhere near the battery life of the iPad at 10 hours unless it uses a larger battery." Wu gives three reasons why he believes this.
First, and biggest among them, is Flash support. According to Wu, Flash will drag the PlayBook's battery performance down, perhaps as much as in half. Secondly, Wu points to the QNX operating system, which wasn't designed for the PlayBook and instead meant for devices that draw more power. And finally, Wu says that RIM's implementation of power management isn't as slick as that of Apple's.
All told, Wu says the best the PlayBook can hope for is six hours of battery life, the same as the Galaxy Tab, and about half of what is offered by the iPad. And that's only after "significant re-engineering," he says.
